This application claims priority to Chinese patent application number 202311072163.6, filed on Aug. 24, 2023. Chinese patent application number 202311072163.6 is incorporated herein by reference.
The present disclosure relates to the field of sanitary ware, and in particular to a faucet.
Installation of conventional faucets is usually carried out under a countertop, so it requires professionals to bend over for a long time, squat, or lie in a dark and narrow space under a basin and use a variety of special tools to complete the installation. This installation method, which requires going under the countertop for assembly and locking, is time-consuming and laborious for faucet installers.
A quick installation mechanism for a faucet on a countertop has been disclosed in the prior art, which comprises a mounting base, a screw rod, a nut, a lifting base that rises and falls as the screw rod and nut rotate relative to each other, and two lever rotating arms. The mounting base comprises an installation hole, and the screw rod is disposed on one side of the installation hole. The two lever rotating arms are pivotally connected to the lifting base. This method of installing the faucet from above the countertop makes the faucet assembly simple, and the faucet housing of the faucet can be installed to the mounting base after the mounting base and the lifting base are fixedly connected to the countertop, so it can be applied to faucets of various structures. In addition, this method only uses a single screw, occupying the smallest space in the installation hole, so that a faucet hose can pass through the installation hole smoothly. This mechanism can be used not only in the installation of the faucet on the countertop, but is also suitable for various styles of faucets and can provide a large installation space. It has the advantages of simple structure, reliability, small installation space occupied, and low cost.
However, the quick installation mechanism needs to be tightly connected to the faucet housing. Since the faucet housing needs to play a supporting role, lower strength materials or thin-walled structures cannot be used, and the overall manufacturing cost is high.
